Get new vector based on angle of two vectors

[Vaei]

Indeed! Both types are stored in the same data type as the elements are only 2-3 floats. The magnitude is then returned by calculating the length, using sqrt(xx, yy, z*z) (Pythagoras). Square root is a relatively expensive operation, so it’s redundant to calculate and store it for all vectors, and is only calculated when needed. It’s up to us to remember what type of value we’re working with when we’re getting and setting a vector. It could be both a location and vector at the same time, depending on what we’re up to.

I hope we’re not going too off-topic Vaei. It’s just for future reference if other users end up in your thread. Good luck with your project.

No such thing as off-topic when it comes to learning new things. It pertains to me also, since I came from 3D art and my understanding of a vector was an XYZ coordinate on a graph I was unaware of the magnitude/direction of a vector. Now things make a lot more sense!

Glad I could help, this vector stuff used to fry my brain too back in the day when I was starting out, but when I eventually got the basics clearly in my head it’s a piece of cake.

Not exactly! there are no two kind of vectors (well there is vector2d with just X & Y but that’s another story) every vector has a direction and a magnitude! what you are probably referring to by “direction vector” is a normalized vector (a vector with a length (magnitude) of 1)… and the “location vector” obviously has a direction and length too!

I think my brain fries regardless of what I’m trying to solve I have spent days on the system I’m working on and its getting tedious so it definitely adds up. But with this I can move to the next phase, I am very grateful for the assistance.

For the sake of argument, isn’t a quaternion stored in a vector4? I guess that’s a dangerous question to ask here
